So no way to just take the vixiecode source - compile it, and install on cm -- if that's what I think you are telling me??
One last think -- I noticed the knock/knockd implementation. Anyway to include fwknop : fwknop: Single Packet Authorization and Port Knocking as the knock daemon implementation?
Currently cyanogen could include vixie cron, but the source as it stands needs to be compiled as part of a whole rom. If you want to simply add it though I believe it has no dependencies, so you could just unzip the update from my site, and copy /system/xbin/cron and /system/xbin/crontab to your phone and they should work. Note that you would have to find a way to get them to run at boot. As that's part of my rom.
on a side note, you could just try out my rom and have it all working
As for knock/knockd. I wasn't actually planning on compiling in knockd (the daemon) as it didn't seem important (since it would be running on a phone). I also picked that implementation because so far as I know its the simplest/smallest, and space on the /system partition is limited.
