Short answer, yes you can now do BGP but you must meet the requirements in the TOS and send the form Brian provided in with the requested information.
You have a regional block allocation from 44.24.127.x which could be requested, or you may be assigned another block based on the application.
Your ASN will be from your upstream. Minimum BGP is /24 CIDR.
So is the plan is to carve up these new BGP allocations out of the existing system or will there be new allocations?
How will the old "tunneled" system work with the new BGP allocations? Will there be entries in the list of tunnels or will they be handled in the default routing?
IE. How will 44.24.126.x clients using a tunnel gateway interact with 44.24.127.x clients on the BGP system?
