Interchange uses Storable if it's available, but otherwise falls back to
using Data::Dumper.

Interchange can do that. You specify the table name with the SessionDB
configuration directive. I'm not sure there's much documentation on it. I 
think your table needs to have at least 3 colums: session_id varchar(64), 
session BLOB (or maybe TEXT), and sessionlock varchar(something). Check 
the mailing list archives for help, and/or read lib/Vend/SessionDB.pm and 
lib/Vend/Session.pm for gory details.

Historically it's been recommended that people not use SQL/DBI sessions,
as it has tended to be slower than using disk files. But some people use
MySQL for sessions in a clustered setup, as opposed to sharing session
files via NFS.

I don't know of any tests just of the page parser.

It really isn't separable from Interchange as a whole.
