on the same network it's fairly common...i think Buffy/Angel was the first cross-network one.
Ally McBeal crossed with The practice (and that might have been network crossing too with Fox and ABC) and L&O crossed all over the place (most notable with Homicide...one of the Homicide regulars joined SVU lster as his own character!)
There's some XF/Millenium crossover too, and then, of course, the bazillion spinoffs where you get one or two eps crossing every once in a while (CSI and Miami or JAG and NCIS, Grey's Anatomy's new spinoff...I'm sure we'll see one or the other character there...)
I think they try to do it so the shows can stand by themselves, and on both Buffy/Angel and SG1/SGA the other half of the eps is not on the DVDs...
