Nowadays, it's just about safe to assume that if a provider 
can offer an l3vpn service, they can also offer an l2vpn 
service.

Most times that ISP's won't consider doing so is because of 
commercial reasons, not technical ones, e.g.:

	o They want to make extra cash from Managed servics,
	  which make most sense in l3vpn scenarios.

	o l2vpn's are cheaper to operate, which means
	  revenues can be eroded. No one like eroded
	  revenues.

	o There is no understanding of l2vpn from a
	  product/marketing perspective. Many times, some
	  product/marketing teams don't want to sell what
	  they don't understand.

Cheers,

Mark.
