David (et al):

Okay, first off, "blog1" "blog2" etc. was just an example -- the  
actual blog names can be just about anything.  For initial testing, I  
tried your rewrite with just "blog" in place, like this:

> RewriteCond %{REQUEST_URI}        ^/(blog)/

No Dice.  "File not found" on anything but the top page of the blog.   
Further research suggests that the problem is that REQUEST_URI is the  
wrong variable (it appears to represent a string being passed to a  
script, rather than an actual path?).  I tried a LOT of variations  
beyond just the above, BTW.  I really think this is the right  
approach though -- I had been leaning in this direction already.  :)

The Apache mod_rewrite docs shows a list of variable names that can  
be used in RewriteCond, but doesn't define them, and I'm having a  
hard time simply finding a list of basic definitions of what these  
variables represent.

Trying to look them up individually is a huge pain because many of  
them mean different things in different contexts, and I keep getting  
sidetracked by similar variables that aren't actually available to  
mod_rewrite!  All the cryptic descriptions with no example doesn't  
help either.  ("This is the path from the root".  Server root/web  
root?  Slashes included/excluded??   Filename included/excluded???  

NEW QUESTION:  Does anyone know where I can find a good list defining  
those variables that can be used in RewriteCond?  Preferably with  
clear examples for each?

OR, is there a good way to test what these variables are  
representing?  Can I stick them in a simple PHP file or something to  
get their values?

Back to the rewrite:

> RewriteRule .                     /%1/index.php [L]

For different blogs, I believe I can do something like this:

But... doesn't that string need something after the slash to  
represent whatever comes after?  I would think something like...

^/([bob|joe|sally])/(.*)(/.*)*   <--that last bit should be: "zero-or- 
more characters followed by zero-or-more (slash followed by zero or  
more characters)"

Thanks again
