mysql lighttpd fastcgi php5 exim.... on a vps not in dh, in debian etch, this on xen, It host my personal blog and streaming 2 streaming servers for radio stations (shoutcast, yes i know icecast, but have to little memory).
For testing on another vps I try a bit more optimized I put myql lighttpd fastcgi php5 dropbear exim-lite (on 64MB) on a openvz, worked as a gallery and smf forum for the total 90 dias I pay in advance...
In home I had one machine (DSL) for testing that is available on the web, it has been up and runnig since debian was in woody, (actually since 2004) it runs lighttpd (since last year, before apache 1.3) php5 mysql on 256MB and K6III 500mhz.

It's not that complicated the hard thing to do is have a very good backup strategy. And I also have my main site on DH.
For those interested on run apache I recomend http://www.amazon.com/Apache-Server-Administration-Second-Library/dp/0782141374/ref=sr_1_11?ie=UTF8&s=books&qid=1196014273&sr=8-11 and maybe the apache coockbook of o'reilly (this last I don't own, the other one I have read and it's very good).
