jxapi.osm.org is, confusingly enough, not running jxapi, but pyxapi 
instead. The Java postgres library has issues with question marks in
queries, which are required for hstore queries to answer a request 
like *[highway], so it got written in python.

The replication lag is pretty consistent at around 1 minute. It's on
reasonable hardware, but no SSDs.

There's some privately run ones. I have one, but it's really just a
side effect of needing the planet in a database. Once you have that, 
running jxapi, pyxapi or cgimap has pretty trivial hardware requirements.
