OMAPI shows signs of being treated like a stepchild for some time, and
I agree that the protocol is too complex to be easilly incorporated in
To get around this I am currently using homegrown middle-ware written
in C (only usefull way to talk OMAPI) that talks XML (SOAP) with
client software written in languages such as PHP.
So we welcome this change, just give us some time to adapt :-)

Exactly, after having spent some time with ISC DHCPD source code, it
seems to me that omapi is anchored pretty well internally in ISC DHCPD.
So I suspect that making a transition by supporting both OMAPI and the
new API externally would not be impossible ?
