First of all, you have to make sure numeric user identifiers are the
same in all three systems, which should not be a problem if you'll be
using Debian-based distros and you're the only user in the system
(you'll probably be uid 1000) -- otherwise you'll have permission issues.

Software versions must also match, especially the major version number,
but remember there're no numbering standards for versions. If software
versions differ, there's a risk of losing or at least damaging
configuration files from one operating system to another, but then
again, if you're using the same versions of Ubuntu it's expected it will
work.

Just for the record, I don't recommend this and I'd rather advise you on
moving personal folders to, say, /srv/data/$user and keep a /home/$user
with (mostly hidden) configuration files and directories for each of the
operating systems, with the exceptions of maybe .mozilla-firefox and
.thunderbird which can be safely handled accross operating systems in
same versions of Mozilla products.

Finally, there're file locking issues with some applications which are
not relying on file system locking anymore, such as OpenOffice.org 3.1,
just make sure to properly close applications before shuting down the
operating system and starting another.

I think I tried this between Gentoo and Debian 2-3 years ago and my
gconf configuration went away. So be careful.

HTH,
