Thanks for the link! Definietly we should some day support various SRSs 
and make them available out of the box for the user. Though I think it's 
not necessary to support various SRSs on a strategy level. Strategies 
are rather low level functionality. When they're used we already know 
the coordinate system and a reference model (cartesian plane/space, 
sphere, spheroid/ellipsoid or maybe some other in the future). The only 
thing we need is the parameters. AFAIU SRSs, projections, EPSG codes, 
etc. should be somewhere on a higher level.

Regards,
Adam
