Works great, I had been meaning to set up FTP for a while, just never got to it. Makes it much more convenient to put new apps and games on the SD, especially considering I usually mess something up on the first few tries and have to tweak directory structures and stuff.
The XML file kept getting corrupted by the HBC, though. No idea why exactly (I'm not very familiar with XML or the syntax for HBC headers), I just used the meta.xml file from another homebrew app as a template and copy & pasted all the ftpii info in. Here it is if anybody is having the same trouble.
Code:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<app version="1">
<name>ftpii</name>
<coder>joedj, srg</coder>
<version>0.0.12</version>
<release_date>20080726000000</release_date>
