A month or so ago I wrote a rant about how Dantz should work with
Alladin and come up with a better compression scheme.
I know that the on-fly compression is difficult to maintain speed,
but it seems like better than 2:1 should be possible. I'm not much
of a wiz at all with compression, however I see modems getting
v.42bis (4:1) on the fly, it seems like a little work and this should
be possible for client and server as well.
Yes, I know that advertised and what you really get are totally
different, but all I know is that if something is advertised at 4:1,
it will be more likely to get at least 2:1 that 2:1 is likely to.
Alladin is cross platform. Dantz covers the same platforms.
Yes, most people use hardware compression, but this is mostly because
the hardware and software compression are likely to get the same
results.
Why would anyone want to write their own compression? I mean, a
license deal from Alladin, who's been doing it since the early days
of Mac, would seem like it would be far more cost effective.
