I'm not one to hold a grudge. Hey, when JackBe said I couldn't download and try their software, I understood. I didn't like it, but I understood.
But let's play fair here.
Someone from JackBe has downloaded Serena Mashup Composer. If I were Fake Steve I might have a field day talking about how, now that they've had a chance to dig into Composer, JackBe must be crying like a girl. If I were Fake Steve I would be suggesting that the JackBe employee is actually getting ready for a job interview with Serena, and that's why he/she downloaded the software. If I were Fake Steve I might even suggest that this is JackBe's way of writing requirements for their next release. "Hey R&D, forget the requirements doc. Just make Presto do what Serena Mashups can do."
I'm not Fake Steve, so I wouldn't say any of these things.
I will say this, however. Presto and Serena Mashups solve different problems. Do you need your data mashed? Presto likely is a good choice. I wouldn't know for sure because I haven't been able to test it, but so I'm told and so I suspect based on the Presto marketing materials. Do you need this mashed data within the context of a business activity? Well, Serena Mashups may be the right way to make use of this mashed data.
The point is that JackBe and Serena should be partners, not competitors.
So JackBe, we've shown you ours. Will you show us yours?
