You have several options (perhaps too many, but that's another issue).

In Galileo, ECF includes version 3.1 of the Apache httpclient, so you 
can use that directly.  The bundle name is org.apache.commons.httpclient.

Or, if you wish, you can use ECF remote services, and one of several 
providers (i.e. r-Osgi, ECF generic, JMS, XMPP, etc).  Here's some docs 
for the remote services API: 
http://wiki.eclipse.org/Distributed_OSGi_Services_with_ECF

There is also much going on now with ECF's support for REST (currently 
using apache httpclient):  http://wiki.eclipse.org/REST_abstraction_for_ECF

Yes.  For usage by P2 and the platform, ECF has written code for getting 
access to the proxy API in Eclipse, and using that information to use 
proxies.  That code is in the source for the following two plugins:

org.eclipse.ecf.provider.filetransfer.httpclient  (httpclient)
org.eclipse.ecf.provider.filetransfer  (jre http impl)

If you wish, you can model your access to Eclipse proxy configuration 
info after what's in the ECF filetransfer provider code.

BUT, you should be aware that there is currently a known issue with 
supporting NTLMv2 with the apache httpclient provider (as the apache 
httpclient provider does *not* support NTLMv2 proxies).  See here for 
more info:

http://wiki.eclipse.org/ECF_Filetransfer_Support_for_NTLMv2_Proxies
https://bugs.eclipse.org/bugs/show_bug.cgi?id=252002

Hope this helps.  If you want more info about this or details, please 
feel free to write questions to ecf-dev at eclipse.org mailing list.
