Plaino instead of "plain old/plain ol'"

[Paul McFedries]

The administrator of another list I subscribe to had to set up the list on a
different server temporarily. When announcing this, he included the
following note:

"There is no online database or a file area or even a picture gallery. Just
a plaino list server."

I found some newsgroup citations where the word "plaino" is used instead of
"plain old" or "plain ol'." Has anyone else encountered this usage? If so,
I'm wondering whether it's use is ironic or if it's just an honest (albeit
chuckle-inducing) mistake.
