I haven't gotten into all that, but I'm sure there is. Here's the link to the homebrew community page thread listing all the current homebrew mods available:
linky. I haven't gotten into the homebrew stuff. Since I use McAfee free on my computers, I haven't made it priority to get into the some of the other features of SW.
I should consider changing one of the settings to closed, so it make it more difficult to hack into, but may run into a few problems that I will need to research first on how to solve.
As for signing up for SW, no you don't have to. It's only if you want to post, and possibly, use the search function in the forums. In SW3, there is an anonomus registration on your system so the SW people can see what hardware people are using and what problem they may be having. If you do register, you just give an email address. I would suggests to do this, since there is an easy find link to the PDF manuals in case you ever need to find them later.
By no means am I knocking Icop. There is a reason it's still around: it works well for it's design.
The one thing I wish they would incorporate, which my router did, was make an easy to read DHCP client list, rather than having to read the DHCP log. Some of my devices--printer server and VOIP--are always checking their IP, so the list if lengthy, where the router just gave a list showing device name and IP. Things I like are the traffic graphs on the networks--day, week, year--live traffic monitoring, a page giving all the network info on the networks, and so forth. It would be interesting to see traffic based in individual devices.
There's still some wire spaghetti, but it's only in a few spots. The wire channels hide a lot of stuff. I found I was loosing a lot of desk space for all my network equipment--router, modem, print server, etc--that it made sense to figure out how to mount the stuff under the desk. One of these days, I'll figure out a cabnet situation to hide the computers I have sitting on the floor under the desk; yes a KVM switch works well to keep save space.
