Design decisions for new Protocol: Adium vs Libpurple

I'm looking to read more on adding a new protocol to Adium as a plugin.

In particular more information regarding writing the plugin in Adium 
(like Services > Twitter, or Services > Bonjour) vs Libpurple.

The  current client is written in C and is tightly integrated to the 
server code base.  Initial attempts to make a client library (similar 
to Bonjour's libezv) have lead to the decision to write a client 
protocol library outside of the current server code base.

Should I write the plugin in Adium (Objc) or look to wrap it inside libpurple?

Where can I find more information regarding the trade-offs between 
Adium native(?) plugins vs libpurple plugin?

Does one API lend itself to new protocols better then the other?

As I understand it, libpurple plugin would give a larger selection of 
IM front-ends (pidgin, finch, Adium). Does it give me more?

Thank you for any advise.
