@Mike Schinkel -
Let me do some digging on this, and clue me further as you think is indicated. I would like to stay with this, and follow through on it. I will return to the Trac page, where I noticed you, and bear down on it.

I have known of this general problem/issue/fear, since the early days of OS. I am aware that conflicts/incompatibilities with Apache have steadily become more prominent, and will get up to speed on the details here.

I think we can take it, that DotOrg wants a plugin library that gives them recognition, and draws users, 'in & of itself'. Ubuntu is pushing 40,000 Debian-vetted & supervised projects ... "at the push of a button". Apple, Google, Firefox ... all the big kids are doing it, and it's big.

I think this is resolvable. I have a heavy money-day tomorrow, but will be back late in the afternoon (Pacific).
