Subject Re: How to handle firefox outputting files, as component?
Date Fri, 01 Oct 2010 19:54:04 GMT

Thanks for the response Richard - was very helpful.

Any sense of how large exchange message bodies can get?  Should we use that itself as the
transfer mechanism or have some other form of transport?

I'm also curious if we want to reuse a bunch of these components we're creating across various
projects and also share them with the community, what's the best way to bundle them up?
