Experience with SQL Relay?

I'm resusitating this three year old thread to ask the same question...

Does anyone have any experience with SQL Relay: http://sqlrelay.sourceforge.net/
It has matured significantly over the last few years.

---snip---
SQL Relay is a persistent database connection pooling, proxying and load balancing system for Unix and Linux.

SQL Relay is ideal for:

speeding up database-driven web-based applications
enhancing the scalability of database-driven web-based applications
distributing access to replicated databases
throttling database access
accessing databases from unsupported platforms
migrating applications from one database to another

SQL Relay supports the following database backends:

Oracle MySQL mSQL PostgreSQL Sybase MS SQL Server
IBM DB2 Interbase Sybase SQLite ODBC MS Access

The SQL Relay client API's support advanced database operations such as
bind variables, multi-row fetches, client-side result set caching and
suspended transactions. SQL Relay has native client API's for the
following languages:

C C++ Perl Python PHP Ruby Java TCL Zope

SQL Relay provides drivers for the following database abstraction layers:

Perl DBD Python DB Ruby DBD PHP Pear DB

An application coded using another database's native client API may be able to use SQL Relay without modification. SQL Relay provides drop-in replacement libraries for:

MySQL PostgreSQL

SQL Relay also features:

command line clients
a GUI configuration tool
extensive documentation

---snip---

It does now support stored procedures for "most databases", though
there are some caveats. (One is that stored procedures for Sybase can't
return result sets, only 'out' variables. I asked the author, David Muse,
about it and he seemed to think it should be straightforward to support.)
