pecl/oauth - possible to send HTTP request myself?

The typical way to use pecl/oauth seems to use OAuth::fetch which does everything including sending the HTTP request using curl or php streams. I'd like to be able to use pecl/oauth to do everything up to and including calculating the signature but then send the request using different code. The reason for this is that I am using a web framework (internal) that can aggregate requests using curl_multi and do them asynchronously (Rasmus surely knows what I'm referring to :-)). I imagine this could be useful also for others who need to make their requests go through proxies. I know that I can call oauth_get_sbs to get the sbs which is probably the most error-prone part of doing OAuth so that's good. But is it possible to take it a step further and get pecl/oauth to return the curl handle it would've used (with OAuth stuff already stuffed in the url or request headers) without executing it? Basically I want to decouple OAuth signature calculation from network communication. Possible? -Marc http://marc-abramowitz.com Sent from my iPhone 3G
