Pushing and Pulling - A love/hate relationship with RSS

My autoblogs pull content from RSS feeds. I can see the future moving to the push type technologies. I think I even remember wordpress or blogger supporting push for their feeds.

Anyone know how to get this push technology working through some type of service, wp-plugin, or wp-o-matic??

If I set wp-o-matic to hit the source RSS feed every X min it can be very inefficient. By the time my blogs get the content it could be 15+ min old already which doesn't sound like a ton but in internet time this is a huge delay

i do it but I don't sell, lease or share the code to do it because it's a lot of fcked up code and i'm still working on it.

like SSIS xml dumps to rss 2.0/1.0/0.9 and atom 1.0/0.3

can't really help you out too much more with info since i do this in a commercial environment

Thanks for the info at least I got a place to start looking now. I will eventually convert everything to move away from pulling every few min.
