We have a networked HP OfficeJet All-In-One. I have the scanner working with the CentOS 5.3, except xsane is ignoring SANE_DEFAULT_DEVICE. scanimage does however take this environment variable just fine:
server1.wendellfreelibrary.org% scanimage -L
No scanners were identified. If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate).

xsane just pops up a little window "scanning for devices", the "no devices available".
I believe I have things properly setup with cups:

I am very interested in this problem as I seem to have it myself. My Printer/Scanner is HPc6180. Do you have HPLIP installed? The version that comes with CentOS is so old that (1.67, I think) that if you have a printer newer than about four years old it won't be supported. I seem to be able to fake the printing part by selecting another printer that should be similar. The scanning part however is not so simple it seems. I installed HPLIP version 3.9.8 and after a grueling effort to satisfy the dependencies, except for dbus-python or python-dbus, it seems to be referred to both ways. HPLIP still claims that it is not installed even though it is. Perhaps my version, although up to date according to yum, is too old. In any case my printer is supported and I was able to scan one frame and then it never worked again. On any attempt to scan xsane puts up a dialog that says "Failed to open device 'v4l:/dev/video': Invalid argument" and then quits. That device I think is the camera which was there and working fine when the single scan succeeded. My Windows XP computer is able to scan so I am confident that the printer hardware is not at fault.
Every time I install a newer version of CentOS (now Linux rwells-cts 2.6.18-128.7.1.el5.centos.plus #1 SMP Mon Aug 24 10:03:38 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux) on a Lenovo X200 Thinkpad this scanner setup is a real PITA. Any way I am looking forward to anything you learn as we go forward.

The beast works just fine as both a printer and a scanner (I have not tried to send or receive a fax). xsane, if given the hpaio:<mumble> url on the command line, works just fine and scanimage is perfectly happy to use the URL defined in the SANE_DEFAULT_DEVICE environment variable. The problem is that the people who will be using it are non-techies and want to be able to just click on the Gnome menu (or use Gimp's File=>Acquire=>scan menu item). This is where it does not work. Somehow, sane/xscan is not finding the device by scanning for it, which seems to be what is needed, since xscan seems to be ignoring SANE_DEFAULT_DEVICE, if the device is not found first by scanning for it.

Maybe your issue is that the environment variable is not set when the Gnome session starts up, so the Gnome menu item doesn't see it. How are you specifying the SANE_DEFAULT_DEVICE value?

*I* am just trying it from the command line (I have not gotten as far as trying it with gnome:
server1.wendellfreelibrary.org% SANE_DEFAULT_DEVICE="hpaio:/net/Officejet_Pro_L7700?ip=192.168.1.253" server1.wendellfreelibrary.org% export SANE_DEFAULT_DEVICE server1.wendellfreelibrary.org% xsane
xsane that pops up its "scanning for devices" window, then its "no devices available" dialog
doing:
server1.wendellfreelibrary.org% xsane "hpaio:/net/Officejet_Pro_L7700?ip=192.168.1.253"
works fine -- xsane brings up the preview window and its main window and is perfectly happy to 'Acquire Preview' (and the preview looks like it is supposed to, so I know the scanner is really scanning).
and scanimage properly uses the value of SANE_DEFAULT_DEVICE with no complaints, except that scanimage -L tells me that no devices were found (as does scan-find-scanner, which does not seem to be checking for networked scanners).
I'm *tempted* to just hack the GNome system menu file to hardwire in the command line argument, except that when an update to GNome will clobber it.
