Over the last weekend, I've been working a bit on a prototype proxy doing streaming html/xml diffs (dubbed mldiffs) based on a shared cache, largely as described here: http://wiki.openmoko.org/wiki/Server:WebProxy Sadly, going by track record, I probably will not have the energy to productize the thing, but maybe it'll provide inspiration and/or a basis for someone to do so. I do intend to get at least the mldiffs going (currently just need to debug the interproxy communication, other stuff is done) and hopefully add rdiff support for non-ml content (during testing I found the mldiffs to be notably better for markup content so I started with that). Then I'll put the (python/twisted) source out there (if someone's really interested for it now, feel free to ask). Image crappification support would be good, but I don't know, it would really require inserting javascript or at least mucking with the (x)html to work nicely with a browser knowing nothing of this. (You know, something along the lines of click the image the first time, and you'll get a better version; second time does what it normally does.) I'm not sure if that's something I want to tackle with. OTOH, simple crappification controlled from a configuration key on the client might be doable with my concentration levels, we'll see. Oh yeah, the interproxy communication thing would need some work as well, currently being plain http. My intent is to personally use ssh -C for a transport service, so I'll get "for free" persistent protocol compression (on top of the ml/rdiff) and encryption for the over-the-air part. Someone more proficient in twisted would likely easily write a nice compact persistent custom protocol with internal async muxing and stuff. Annyway, thought I'd mention this even though, as said, my proxy is in a prototype stage, because, you know, this being an open phone, there's no need for one to limit oneself to proprietary solutions, even if there's not a free one available right this instant. -- Mikko Rauhala - [EMAIL PROTECTED] - <URL:http://www.iki.fi/mjr/> Transhumanist - WTA member - <URL:http://www.transhumanism.org/> Singularitarian - SIAI supporter - <URL:http://www.singinst.org/> _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
