[plt-scheme] PLT and MySQL

I'm trying to figure out where things stand with MySQL driver(s) for  
PLT Scheme.  On 3-Feb-2007, Hans Oesterholt-Dijkema wrote that he was  
working on a driver for sqlid, sqld-mysql.  I found great drivers for  
PostgreSQL on Schematics, which is wonderful (PostgreSQL is great),  
but I have regular mundane need to interface with MySQL.  I currently  
talk to MySQL with Perl, Ruby and Python, but would like to move to  
PLT Scheme.  I looked at Eric Knauel's Myscsh and José Silva's mr- 
mysql, which are both interesting.

Is anyone actually using MySQL with PLT Scheme, enough to recommend  
one package over another?  Is there an ongoing effort somewhere that  
just needs additional volunteers to implement a good design, or is  
this one of those times it's best to dig in and start afresh?
