I just read Clemens' comments on my last entry. I really appreciate it!
CoRegisterSurrogateEx() sounds like something I really want to look into. It's a pity we won't have COM+ 1.5 on our hands any time soon (besides RTM being so far away, it will take serious time for the adoption of .NET Server).
I'll definitely look this time into your ServicedComponentEx stuff, which I missed last time. The Load Balancing stuff sounds interesting, too, although there doesn't seem to be much documentation on it.... I'll see if I can spare some time during the weekend to play with it.
