Here is mine:

1. Put the OTP source code in CVS and make it accessible.
2. Use nice patches that people send :-)
3. Rentrant and thread safe emulator (SMP)
4. binary syntax updates, bitgroups! possible add -list -tuple and 
-msb|-lsb for bit reversal. One more syntax improvment whould to add 
record support in bitsyntax, something that I have to do by hand to day:
	<< X/#r >>.

5. charactar support UNICODE !!! with ord/chr/upper/lower support
6. module as objects, and in external format. This means that modules on 
disc should be in extrnal format. Think of the following:
	{ok,Bin} = file:read_file("somemodule"),
	Mod = binary_to_term(Bin),
	apply(Mod, my_func, Args).
	register_module(Name, Mod)
This was done in as a prototype in multithread erlang and worked very 
7. nodes as objects. Today node name is somed kind of DNS name, this 
does not work for multi-protocol. The #<Node> should be something uniq 
not coded as an atom.
8. subnodes. (from SafeErlang). With orwith out SafeErlang, subnodes 
could be a nice way to handle safe environments with own name spaces 
etc. Possibly restrictions on number of processes and execution time etc 
could be added.
9. I think that will keep you busy for a while :-)
10. Not ready yet ?

Have fun/0.
