Pascal,

I suppose it is nice for p2 to have some abstraction layer, so you can 
flip implementation if one you are currently using does not work. From 
what saw that is what just happen, so p2 switched from urlstream-based 
implementation to httpclient-based one and later one you can switch to 
something else when you'll find issues in httpclient without changing p2 
code. It is great, but I am concerned that ECF isn't really focused on 
getting a robust transport implementation and only creating wrappers for 
other frameworks that known to have their own issues. E.g. httpclient 
does not completely support ntlm auth.

Also, there is number of technologies won't be able to use ecf layer, as 
they use different abstraction layers, such as axis or xml-rpc and their 
own implementations are using http client under the hood. As far as I 
know, those abstractions are required by some of Mylyn connectors.

regards,
Eugene
