[OSM-talk] 'Offset path' distances

Hello all,

I'm adding a feature to Potlatch whereby you can select a way, choose  
'Offset way', and a new, parallel way will be created a certain  
distance away.

Obviously you'll be able to specify any distance you like, but I'd  
like to offer some presets in metres - for dual carriageways, canal  
towpaths, etc. etc.

Could anyone suggest what distance, and for what use, these presets  
should be? (e.g. "narrow canal towpath, 5 metres" - i.e. the offset  
from the canal centreline to the towpath centreline)

cheers
Richard
