Thanks for the work. I don't know who the active CIPE users you polled are so 
I'm kind of in the dark about the motivation of some of your changes, so 
please have these users email me or the mailing list so I can get to see the 

Here's some of my roadmap.

1. Periodic DNS resolving will be going into cipsrvr.exe to facilitate 
LAN's between dynamic IP hosts, among other things.

2. The Control panel will go away and will be replaced by an management 
utility. The whole control panel invocation thing has been a pain in the butt 
for me.

3. The format of the key specification will change to allow keywords to 
where and how the key is stored. e.g file:/a:\statickey.txt or 

Further I have some issues with your changes

1. The control panel should already have this behaviour. Was there a bug that 
prevented this ?

2. I disagree with the asterisk representation. It's too hard for the 
administrator to confirm that he/she has it done right. I repeat it is NOT A 
PASSWORD AND IT IS STORED IN CLEARTEXT ! If you have problems with this 
representation then you need to chase it up with Olaf. I am strongly 
disinclined to merge this feature as the stated mandate of this project is to 
follow Olaf's direction. It appears that the way forward with this is pkcipe.

3. Nice

4. Redesigned how ? (I'll have to really read the code now, won't I  ?) Does 
the combo box only allow the local IP addresses or does it let you type in 
what you want anyway ?

5. Only necessary if  you have the combo box in 4.

6. Mostly good. DNS resolution should not be done here, though

7. Nice. I don't particularly want any DLL dependencies that won't allow the 
suite to run on NT4.0. The binary distribution supports and will continue to 
support all NT kernel Windows versions.

8. Good idea on both counts.

10. Please explain this mechanism to me.

It would seem that you've already made your fork available for general 
comsumption with confusing version info. CIPE-Win32 is still prerelease, 
hence the "PRE" in pre15 (there are still one or two issues with the kernel 
driver that need to be exorcised once and for all). So, I'd suggest that if 
you're going to continue with providing it as a full distribution then you 
should change the version info to indicate that and to include your name or 
something to indicate that this is a fork and not the "official" version.. 
That way, if someone running your version has a question about it, then they 
can ask you.

Thanks for the good work.
