Well, I've decided to post my modern/sci-fi skirmish rules the web. I think the infantry rules are finally at the point I want them to be at. Games seem to flow well, and the mechanics work. I have posted the rules to this newly created yahoo group, for both my own and my buddy's rule writing ventures: http://ca.groups.yahoo.com/group/teatimegames/
If you have an aversion to yahoo groups, you can download the rules here: http://www.mediafire.com/?j2uz202iv2rs7k8
The nice thing with the yahoo group is it easily facilitates discussion of the rules, but it's your call.
These rules are still very much in development, so feedback is welcomed.
Vehicle rules (and other things) coming soon.
