This is something you always need to do regardless of the project IMHO, you need to check that all libraries you use are fine with your license ASO, I don't see how RTCWeb is different here.

What is "huge" for you these days? Assuming it's a JS library, it can be compressed.

Yet you are bringing a new iterop issue to the table: SIP or XMPP <-> the protocol in the browsers.

Well, it's a client, not a server, so performance will definitely not be an issue.

I didn't get that last part, do you mean that plugins are forbidden in RTCWeb client? Anyway, JS is enough. I'm not sure about Googles' plans with regards to NaCl, but if they plan to push that technology forward so that other browsers implement it, the signaling could even be done in C, in case you are worried about performance, though I know it's not an issue.
