Online e-card programs should support inking!

Earlier in the morning I was working on sending out e-cards from Hallmark's online site, and I realized when I woke up this morning, how much easier it would have been if the cards supported inking. Once you have previewed a card design, you get the option to "Personalize" it by typing in text. What if you were able to do this by inking? This thought came about because last night I also sent my Mom a handwriting e-mail, which she announced that she loved because it felt more personal. I think that it would be great if companies like Hallmark, and other online e-card providers, would support tablet inking technology. Just my 2 cents. What do you think?
