[NeutrinoAPI]

While this can be true for some problems i'm not sure you have really thought about the details of the problems we solve other than a cursory glance.

Firstly, although python has loads of great open source libraries, you wont find any that can do all the things we can do.

Secondly, the volume of data that needs to be maintained and updated (on daily basis) is massive and way out of the scope of most projects (e.g. we maintain databases with more than 5 billion records which have to be updated daily).

Finally, although some of the APIs could run in a 100% local environment (we are looking into some ways to distribute this way) most either require a constant fresh data feed or need to connect to external systems e.g. to make and HLR query you must connect to the SS7 network which is not easily obtained and simply something most developers don't want to have to deal with.
