Arduino based UHF pager network - POCSAG encoding

Before I start too seriously on my project, is anyone else working on an arduino based UHF radio to send a signal to a pager using POCSAG encoding?

I don't want to run a PC with this setup.

I would like to be able to monitor different pieces of hardware like a windmill, and if it goes down or starts acting up I would like to be notified via pager.

I would also like to have access to my Arduino via radio frequency for any admin operations and upgrades.
