I think original routing methods are not easy to use and have drawbacks :
- eBGP is not available to end-users, or even to small teams or repeater
operators. It requires network skills, and access to telecom operator data centers.
I think end-users or teams should not try to use eBGP unless they want to do it as another learning project as part of their AMPRnet gateway.
Announcing your AMPRnet allocation on internet is simply a matter of telling your colocation/VPS hosting company that you have portable address space that you want to announce on internet and route that to your server or router. That is a standard change in their portfolio, they do that for lots of other customers and for them it is a simple matter of configuration in their existing network. They know how to do it and they already monitor it.
When you do it yourself, you will have to get an AS, peering, setup your router, cope with the vast amount of routes and the processing and storage they require, etc. Not something to embark on lightly, and usually not necessary at all.
