<font face="arial" size="2"><p style="margin:0;padding:0;">I have an awkward worry that the functionality here is expanding to fill all possible space on the machine, so it is less a router than a complete "home appliance".</p>
<p style="margin:0;padding:0;"> </p>
<p style="margin:0;padding:0;">On a machine that has almost no internal isolation capabilities, lurking potential alignment bugs whenever the kernel is updated by the x86 maintainers, vulnerable to the first compromised service, it may be a bit risky to load on to the system every app except the kitchen sink.</p>

<p style="margin:0;padding:0;">My personal bias would be to make a darn good router, and leave the other stuff entirely out of the picture.</p>
