Oh well. I am always look forward for a day that I can logged on to Genie.
Now all I wanted to know is "How much better is HP compared to AA?"

By the way, AA has custom filters too. The default is LZW, but there are two
others that came with AA. But unfortunately one of them is too slow, and
the other one is too inefficient. Econ promises to produce more filters for
AA, and will produce a card that can upload the process to it, thus speeding
up the compression/decompression for 50 times.

: Andy - I can't remember, can HP choose a compression scheme based upon
: filetype?  For example, if it senses a MOD or an rSound, can it run
: ACE instead of LZW?

AA did that. AA is even so smart that it will not compress Inits, DAs, etc.
You can change all these using the configuration dialog. 

One thing AA reserved is "dynamic expansion", I am not sure what is that. 
But looking forward to any improvement in AA to make it much faster.

(Hint to Econ: take a look at what HP offers and try to add more features! -
or else we will move to HP!)
