[erlang-questions] The future of Erlang and BEAM

Hi Miles,

Well, although I didn't mean to write a new language (I meant writing 
Erlang-for-JVM, but rather as a DSL), I agree that Erlang IS very mature 
and stable. And of course, it started as a industry-level language, so 
it's designed to operate as such.
I was just wondering if and maybe we could benefit from being hosted on 
JVM which is, although not THAT industrial-level, also capable of being 
used in such conditions and is most popular VM on the world (so far). 
The obvious advantage of using Erlang in such conditions would be (apart 
from above) just not using verbose Java, which is big plus on it's own 
:) (in my opinion).

So, if we could have both of the worlds, i.e. industry-level of OTP and 
JVM ubiquity, that would be something huge I think.

Greetings,
Radek
