Actually I'm pretty sure that if further encryption takes place, by having the tools you need to currently download sounds on a caller from the internet, I would have the tools to continue downloading them after the company keeps up with the times.
I also believe that newer callers were designed with this in mind.
Also, with the price of bandwidth. It does get more expensive with more traffic. So what bandwidth was costing 3 years ago with (for example only)10,000 users per year may have been nominal, if you have (for example only) 150,000 users last year, your bandwidth bill goes up considerable.
may not be a webmaster, but I can guarantee you that I know what I'm talking about there, based on what I've personally seen with other websites.
I'm also not a believer in keeping indefinately products that may have fallen by the wayside with outdated technology. Not just e-callers, but all sorts of hunting/shooting/calling gear are rapidly being updated as we speak. I used to kill coyottes with a Savage 99 with a Weaver K-4 on it in .243 using 100 gr. soft points....Will it still kill 'em. Sure! But, I like to keep up with the times and shoot the latest in rifle, scope, bullet technology...and it works well for me.
I also don't expect Savage to fix a problem with my 40 year old 99.....I figure I got my money's worth a long time ago out of that.
