I really like Xeoma. I use it on Ubuntu but have a few things I'd like to suggest:
1. enable tabbing between fields in camera setup
2. enable "." character in setting up camera IP addresses (it doesn't seem to work for me)
3. create a iPhone app!
4. create a way to easily revert to or save your last settings (or at least save more versions of settings)
Number 4 is the most important to me because I find that the settings get wiped out pretty easily when poking around in the menus and all the cameras have to be set up again from scratch.
Thanks
Dave
