[Dxspider-support] Problems with command " dx by "

Angel, Charlie and others

I shall be having a tidy up over the next couple of weeks. If this is
the consensus I will happily remove the 'dx by' or else raise the
privilege for it so that it can only be used by 'trusted' users.

I shall be incorporating all the various patches that I have received
from various people and then doing a full release.

What happens then I am not really certain. I think the software is as
developed in its current state as it can go. I have made various
attempts at adding a 'new protocol' but without any lasting success. 

The problem is that that core of the software needs to be rewritten and
a completely different way of passing the necessary data between nodes
needs to be used. It also could do with some things written in C adding
to it but that will bring some distribution problems for our Windows
users.

My domestic situation appears now to be stabilising (to the extent that
I am now living in a completely different place with a different family)
so hopefully I may be able to devote some time to writing code again.

The real question is: is it going to be worth the effort of doing a
fairly substantial rewrite of the core code? Do I really need to
maintain full compatibility (particularly with respect to user/node
lists) to non-dxspider nodes. If I never see another PC16/17/19/21/39
again - it will be much too soon.

Please think about it and discuss.

Happy New Year to everyone
