Can I create an EC2 MySQL slave to an RDS master?

No.

Here’s what happens if you try:

mysql> grant replication slave on *.* to 'ec2-slave'@'%';
ERROR 1045 (28000): Access denied for user 'rds_root'@'%' (using password: YES)
mysql> update mysql.user set Repl_slave_priv='Y' WHERE user='rds_root' AND host='%';
ERROR 1054 (42S22): Unknown column 'ERROR (RDS): REPLICA SLAVE PRIVILEGE CANNOT BE GRANTED OR MAINTAINED' in 'field list'
mysql>

Note: this is for MySQL 5.5, which is unfortunately what I’m currently stuck with.

For the past few years I’ve been hosting this site on an old desktop in my basement on my FiOS connection. This was one of the things I really liked when I switched from Cablevision to Verizon - they don’t block port 80 inbound, so I didn’t have to pay for separate hosting. My “server” was an old AMD desktop with 1 gig ram and a sata drive. It was ok; my site was slow but I was ok with that. I configured Nginx to cache the static assets which sped most things up to “ok” levels but it was never fast.

Migrating RT from mysql to postgresql.

So I wanted to move our old RT 3.6 system to a new VM running a clean CentOS 5.3 x86 install and RT 3.8. I got RT installed but the 3.6 system was running on MySQL, which sucks (still), and I wanted to move it to Postgres, which rules (more and more each day). So Googling for “migrate rt from mysql to postgresql” brought me here. I tried the procedure listed there but it wasn’t quite working for me. my2pg.pl and mysql2postgresql.perl both caused segfaults when I tried to run them. I realized I was on my own, and it wasn’t really that bad.
