I think its important to understand why shared hosts dont like PECL.
Some of the main reasons IME is that they 1. Dont know the author of the package 2. Dont trust the package to be secure 3. Dont know if the package will have a knock of effect on server stability. They know the core package and they know its done by a set of core developers, even though the pecl extensions are written by many of the same developers as core they are still reluctant to use it. To make PECL more widely accepted we need to find a way to convince the hosters that these packages are of as good a quality as the core itself. What would be really nice is if extensions could be enabled / disabled using .htaccess files or apache config files for example. This would allow a shared hosting to make a certain extensions available to just a few users. This I think would lower the barrier of resistance. Regards Marco
